| 1 | The Soft-Strain Effect Enabled High-Performance Flexible Pressure Sensor and Its Application in Monitoring Pulse Waves显示文摘Flexible and wearable pressure sensors attached to human skin are effective and convenient in accurate and real-time tracking of various physiological signals for disease diagnosis and health assessment.Conventional flexible pressure sensors are constructed using compressible dielectric or conductive layers,which are electrically sensitive to external mechanical stimulation.However,saturated deformation under large compression significantly restrains the detection range and sensitivity of such sensors.Here,we report a novel type of flexible pressure sensor to overcome the compression saturation of the sensing layer by softstrain ffect,enabling an utra-high sensitivity of~636 kPa^(-1) and a wide detection range from 0.1 kPa to 56 kPa.In addition,the cyclic loading-unloading test reveals the excellent stability of the sensor,which maintains its signal detection after 10.000 cycles of 10 kPa compression.The sensor is capable of monitoring arterial pulse waves from both deep tissue and distal parts,such as digital arteries and dorsal pedal arteries,which can be used for blood pressure estimation by pulse transit time at the same artery branch. | Yue Li Yuan Wei Yabao Yang Lu heng Lei Luo Jiuwei Gao Hanjun Jiang Juncai Song Manzhang Xu Xuewen Wang Wei Huang | 2023 | Research2023，，1： | 0 |
| 2 | Three-dimensional hierarchical Ca_(3)Co_(4)O_(9) hollow fiber network as high performance anode material for lithium-ion battery显示文摘Transition metal oxides have high specific capacity as anode materials for lithium-ion battery.But aggregation of particles and volume expansion during lithiation/delithiation restrict their application.In this work,a three-dimensional hierarchical Ca_(3)Co_(4)O_(9)hollow fiber network assembled by nanosheets is prepared by an electrospinning combined with heat treatment method to overcome these issues and to boost its lithium storage performance.As-synthesized sample possesses excellent cyclic stability(578.6 m A h g^(-1)at 200 m A g^(-1)after 500 cycles)and rate performance(293.5 m A h g^(-1)at 5000 m A g^(-1)),much better than those of commercial Co_(3)O4.Furthermore,the fast kinetics of the three-dimensional Ca_(3)Co_(4)O_(9)hollow fiber network is also confirmed by the variable scan rates CV tests and the EIS measurements,which is dedicated to the specific hierarchical hollow fiber network structure that provides shorter ion transport distances and higher electrical conductivity.This work supplies a universal approach to improve the electrochemical performance of transition metal oxides for lithium ion batteries. | GUAN ShouJie FAN QingLu LIU LiYing LUO JunCai ZHONG YiCheng ZHAO WeiMin HUANG ZhenCai SHI ZhiCong | 2021 | Science China(Technological Sciences)2021，64，3： | 0 |
